The truth, “is going to come out sooner or later,” Pardo tells In Touch. And he believes that the real story is that Simpson and Khloe’s mom, Kris Jenner, conceived the youngest Kardashian sister during a drunken hookup.

Kris denies the claim, telling In Touch, “This is an absolute lie and not true. I have never had an affair with O.J. Simpson.”

But Simpson’s manager hints that he could be preparing to tell his side of the story with or without Jenner’s consent. If a judge grants Simpson’s request to be released pending a new trial in December, Pardo claims, Simpson plans to air more information about his relationship with the Kardashians.
